Abstract
We report on a first search for resonant pair production of neutral long-lived particles (NLLP) which each decay to a bb-bar pair, using 3.6  fb(−1) of data recorded with the D0 detector at the Fermilab Tevatron collider. We search for pairs of displaced vertices in the tracking detector at radii in the range 1.6–20 cm from the beam axis. No significant excess is observed above background, and upper limits are set on the production rate in a hidden-valley benchmark model for a range of Higgs boson masses and NLLP masses and lifetimes.
